I'm working primarily on Windows XP, but my solution needs to be cross platform.
The problem is that I need more than the fact that a file has been modified. I need to know what has been modified in that file. I am needing to synchronize the file on a remote folder, and my current solution, which simply copies the file if a date comparison or a content comparison, becomes a bit unmanageable for very large files. Some of the files I'm working with are hundreds of MB in size, or larger. So I need to skip copying a hundred MB file that has had only a few bytes changed and instead identify which few bytes have changed and where those changes are. I was thinking having a module that worked below the file system level, at the device level, might be a place to look for a solution. -- http://mail.python.org/mailman/listinfo/python-list
